The supervolcano Yellowstone Caldera, considered as an active volcano, covers a 25 mile by 37 mile area of Wyoming. During its last big blast about 640,000 years ago, a large crater was formed in the area. After the big blast, the supervolcano averages 30 minor eruptions. The most recent eruption of the supervolcano was 70,000 years ago that produced the areas’ flat landscape.
Scientists noticed in 2004, that the Caldera‘s ground rises at the rate as high as 2.8 inches (7 centimeters) annually.
Hang on baby...if that super quake blows, it’s lights out for the earth.
